Cc2531 zigbee adapters support

I’d like to play with Mozilla WebThings. I’d install it on my Raspberry 3 to control some zigbee bulbs (still to buy).

I read DIGI Xstick and Conbee zigbee adapters are supported but they’re not cheap or easy to find here in Italy. Are the cheap cc2531 usb adapters a viable alternative?

There is a pull request to add support for the cc253x: https://github.com/mozilla-iot/zigbee-adapter/pull/101 but I’ve been so bust with other things that I haven’t had a chance to review and test it.
